Upgrade from NB 8.0.2 to NB 8.1

I trying to profile my code and cannot find much documentation on the 8.0.2 profiler.  I upgraded to 8.1 since there was a UI change from 8.0.2 to 8.1. Tried loading both SE and EE editions and get the same issue trying to open maven projects that I have been working on with 8.0.2 without any issues.  This is the exception I get trying to open a project. Bug has been generated but I need a workaround so I can continue profiling.
